EcoFlow 400W

400W Rigid Solar Panel

Whether you live completely off the grid or want to supplement your home's electricity with clean solar power, this 400W rigid solar panel delivers dependable, high-output performance. Designed to generate and store renewable energy, it helps cut your monthly utility costs while giving you a reliable backup during unexpected outages. Mount it on your rooftop and start harnessing the sun's potential from day one.

Superior Solar Energy Conversion

Built with premium monocrystalline silicon cells, this panel achieves an impressive 23% energy conversion efficiency — outperforming many comparable panels in its class. That means faster charging speeds and more usable power from the same amount of sunlight. Pair it with your current PV array or a dedicated Power Kit system, and the built-in MPPT controller will automatically fine-tune the energy harvest for peak performance.

Waterproof & Built to Last

Engineered from the ground up for outdoor exposure, this panel carries an IP68 waterproof and dustproof rating along with a corrosion-resistant aluminum alloy frame. It is certified to handle wind gusts up to 130 mph and bear snow loads as heavy as 113 lbs per square foot — so it keeps collecting energy through storms, rain, and harsh winters alike.

*Water and dust resistance were evaluated under controlled laboratory conditions meeting IP68 standards per IEC 60529 (submerged to a depth of 1 meter for up to 72 hours).
*Properly mounted panels can endure a dynamic wind pressure load of 2400 Pa (equivalent to 130 mph winds) and a static snow pressure load of 5400 Pa (equivalent to 113 lbs per sq ft of snow).

Off-grid & On-grid Ready

This high-output panel adapts seamlessly to both grid-tied and fully off-grid solar configurations. Use it to bank energy for power outages, slash your monthly electricity bill, or supply standalone power to a remote cabin or RV. Whatever your setup, it integrates effortlessly into your existing solar ecosystem.

Universally Compatible

Equipped with a versatile all-in-one solar connector, these panels work with virtually any 48V power system right out of the box. The included 300 mm charging cable gives you generous clearance to arrange multiple panels side by side across your roof, maximizing total solar input without awkward cable management.
